Cold working of metals: When considerable deformation is required in a metal wha

Cold working of metals:
When considerable deformation is required in a metal what can be done to avoid brittleness or rupture?
Are closer dimensional tolerances and better finish advantages of hot forming or of cold forming?
In which type cold forming or hot forming is more massive machinery required to form a given size part?
What must be done to hot-rolled steel in the mill before it can be cold finished?
Cold-rolled steel strip is the material used for many products such as auto bodies and kitchen appliances.

Cold-rolled steel strip is the material used for many products such as auto bodies and kitchen appliances. How is it made?
How is the process of making wire similar to that of cold drawing bars?
Cold-forming upsetting machines can make parts from wire stock at a high rate of production as much as 36000 parts per hour. What kinds of parts are usually made on these machines?
Larger more complex products than those of Question 12 are made from bar stock on cold-forming machines that do combined operations in a sequence of operations. Name two products made on these machines.
Threads cannot be rolled on gray cast iron die cast metals and 301 stainless steel. Why not?
Would extrusion or cold rolling be more practical for producing various odd-shaped cross sections from soft metals such as aluminum in short runs? Why?
When press brakes or bar folders are used what is the process called: forming shaping bending or drawing?
Large steel pipes are electric arc welded after being formed. How are small round square or rectangular tubes joined at the seams after being formed?
If thin aluminum panels 4 by 8 ft. needed a shallow ribbed form to give them rigidity and 300 were required which would be more economical to use standard drawing dies or a rubber pad press?
